Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of the filing date under
35 U.S.C. 119(e) from U.S. Provisional Application For Patent Ser.
No. 61/334,749 filed on May 14, 2011, which is incorporated herein
by reference.
TECHNICAL FIELD
[0002] The present application relates to a putter head and putter
including the putter head that is used for striking a golf
ball.
BACKGROUND
[0003] The sport of golf is played on a playing area referred to as
a golf course. The golf course includes a number of sequentially
numbered holes. Each of the holes of the golf course has an initial
ball striking location, referred to as the "tee" or "tee-box", a
putting green containing a hole, and an area extending between the
tee-box and putting green, referred to as the "fairway". The
"rough" are areas that flank the fairways on each hole of the golf
course. The "fringe" is an additional area that surrounds the
putting green.
[0004] While playing a round of golf, players strike a golf ball
with a golf club to advance the ball from an initial ball striking
location to one of several numbered putting holes. During normal a
round of golf, a player usually plays 18 sequentially numbered
holes that are laid out on the golf course. The object of the game
of golf, on each hole, is to advance the golf ball from the initial
ball striking location into the hole in the fewest number of
strokes.
[0005] A player usually carries several different golf clubs during
a round of golf. Each golf club is identified as a wood, iron, or
putter according to its ball-striking portion. A wood is generally
used to strike the golf ball from the initial ball striking
location (ie, the tee-box), or to strike a golf ball to advance it
a long distance. Irons are generally used after the initial shot on
each hole to advance the golf ball closer to the putting green. A
putter is used to strike a ball from a location on the putting
green into the hole. In the case of a putter, the ball-striking
portion includes a structure to strike the ball such that the ball
should move along an intended path along the putting green surface
and remain on the green surface throughout its entire travel into
the putting hole. Putting is one of the most difficult and
unforgiving aspects of golf. Players spend a significant portion of
their practice time in perfecting their putting to reduce the
number of putts needed during the round of golf to get the golf
ball into the hole on each hole.
[0006] The accuracy of a putting swing depends on several factors,
including where the strike face impacts the ball, the location of
the center of gravity of the putter head, and the rotational moment
of inertia about a vertical axis extending through the center of
gravity of the putter head. Moment of inertia affects the club's
ability to resist twisting from an off-center hit when the ball
does not impact the sweet spot of the putter head. The greater the
moment of inertia, the less likely the club will twist in the
player's hand and cause a misdirected shot. Redistributing mass
away from the striking face toward the rear of a putter head tends
to increase the moment of inertia about the impact location.
SUMMARY
[0007] Disclosed is a golf putter head comprising a main body
comprising a face portion having a toe portion and a heel portion,
a top portion, and a sole portion, wherein said top portion
comprises a partition defining a plurality of cavities in the top
portion; and at least one weight removably fastened within each of
said cavities.
[0008] Also disclosed is a golf putter comprising a putter head
comprising a main body comprising a face portion having a toe
portion and a heel portion, a top portion, and a sole portion,
wherein said top portion comprises a partition defining a plurality
of cavities in the top portion, and at least one weight removably
fastened within each of said cavities; and a shaft extending
upwardly from said putter head.
